Detectives from the NYPD investigating allegations of attempted rape by Giants defensive tackle Jay Bromley have revealed they are now looking into whether his accuser extorted a Hollywood actor over an alleged sex tape, The New York Post is reporting.

Bromley, 23, told police that the woman tried to shake him down for money after they met for sex at a Midtown hotel early Saturday morning.

According to the Post, the woman reportedly targeted actor Taye Diggs —by threatening to leak a sex tape of him, her and another woman.

Sources within the NYPD are citing threatening Instagram posts she made after the sexual encounter took place.

Detectives are also aware of a possible third unidentified extortion victim the woman had targeted sources said.

The woman uploaded a brief clip of a video clip to Instagram showing her and the 45-year-old Diggs, in what appears to be in the hotel room of a swanky hotel.

Diggs, who has starred in roles including “How Stella Got Her Groove Back,’’ in TV’s “Murder in the First” is seen lying on a bed, fully clothed, while the woman, who can be seen licking her lips, is recording.

The video was accompanied by a profanity-laced message addressed to Diggs, where the woman threatens to release “all seven parts of this video, bitch.”

“I will air out this entire video piece by piece of u licking both me and my bitch p—y and ur f–k­ing number if u don’t get ya s–t right,” she wrote.

“Act dumb if u want to. I have footage of u on all kind of drugs, and sucking on my c–t hoe.”

According to the site Diary of a Hollywood Street King, a week after the video surfaced, Diggs ended up paying Bromley’s accuser “a large undisclosed sum of money” to cover up the sex scandal.

The alleged victim confirmed to The Post that she posted the video featuring Diggs, saying: “Yes, I had an altercation with an actor in the past. I went to social media. A lot of girls go to social media and blast off when they are upset.”

But she has maintained, “I never extorted that man,” and, “That man never gave me a dime.”

Bromley’s met his accuser on Instagram, sources have said.

The woman told police officers that Bromley became violent after she became sick while performing a consensual sex act at the Hyatt Herald Square hotel. Afterwards, she accused the New York Giant of hitting her with his vehicle as he drove away from the hotel.

“I’ll be honest with you; I threw up. I agreed to s–k him off, and I threw up. I was drunk, and that’s when he blew up,” she told The Post.

The woman refused to give details of the alleged rape, saying, “I’m not getting into all that.’’

“My knee and back are injured,” and added that she was “really traumatized” by the incident, the woman said of the injuries she sustained after allegedly getting hit with Bromley’s car.

Bromley refused to comment outside his home in Secaucus, NJ, on Sunday.

“We have reviewed the allegations against Mr. Bromley and believe no crime has been committed,” said Bromley’s lawyer, Alex Spiro of Brafman & Associates.

Diggs could not be reached by phone or at his Tribeca apartment, and his agent declined to comment, referring questions to a publicist who did not return phone and e-mail messages.
